The invention discloses a wireless power supply device and a wireless power supply system for electric equipment. During the electromagnetic field or electric field coupling of wireless transmission of electric energy, matching opposite property of a power supplying-receiving coil is very extremely sensitive to the transmission efficiency of electric energy. A power supply end of a tramcar is composed of rail lines and a mobile power supply block, wherein the rail lines are connected with a power supply and are arranged in sealed pipelines on the ground between rails below the bottom of the tramcar, the mobile power supply block is connected with the rail lines and opposite to a current collecting shoe on the outer side of a sealed body wall through magnetic attraction, and the effects that the mobile power supply block which is always opposite to the power supplying-receiving coil advances along with the tramcar synchronously and provides close-range wireless power supply in real timeare formed; the configuration amount of energy storage batteries of the tramcar can be reduced when the real-time power supply electric energy is directly consumed in tramcar movement, thereby savingcost, space and weight, enhancing space utilization effectiveness, aesthetic degree and movement efficacy, and having great comprehensive value; and through marking and positioning a power supply coil when the electric vehicle is being charged, a power receiving coil automatically corrects position by means of an alignment mechanism, thus energy transmission efficiency is improved, and a foundation is laid for implementing a simple and beautiful parking lot and acquiring all-weather non-contact charging for outdoor parking spaces.

The system comprises a Flash file storing block managing module, a file information managing module, a file operating and managing module and a specific operating and managing module for a signal system. According to the Flash file storing system, the actual storing space is managed by effectively arranging block addresses of a Flash chip array, the block addresses of the file system meet the using requirement of the high-speed Flash file storing system, a set of flexible file managing APIs are provided, and meanwhile a specific operation interface is provided for a signal recording system.

The invention discloses an automatic clamp upper cover fetching device for automated production of circuit boards. The automatic clamp upper cover fetching device comprises a rack, a positioning mechanism and a die fetching mechanism, the positioning mechanism and the die fetching mechanism are mounted on the rack, a first mechanical arm is horizontally inserted at the top of the rack, a second mechanical arm is vertically inserted on the first mechanical arm, the die fetching mechanism is mounted on the second mechanical arm, a lifting rod is mounted on the second mechanical arm, a sucker frame is fixed at the lower end of the lifting rod, a lifting cylinder is fixed on each of two sides of the sucker frame, a lifting cylinder extensible rod is connected with a lifting claw, a sucker is mounted on the undersurface of the sucker frame, upper cover buckles are symmetrically arranged on two sides of a clamp upper cover, buckle grooves are symmetrically formed in two sides of a clamp baseplate, and the upper cover buckles are embedded in the buckle grooves for matched connection. The automatic clamp upper cover fetching device can realize automated clamp upper cover fetching during circuit board assembling and is suitable for large-batch production, stable in control and convenient to maintain.

A balancing weight dispenser has a balancing weight storage space for storing a belt of balancing weights on a reel, a belt guide, and a cutter at one end of and / or along a length of the belt guide. The cutter comprises a knife, which is fixedly attached to the balancing weight dispenser. For delivery of a required amount of balancing weight mass, the belt of balancing weights is pulled from the reel until the desired number of balancing weights has been obtained. In the next step, the belt of balancing weights is cut, preferably between two adjacent balancing weights, to separate the selected portion of balancing weights from the remaining belt of balancing weights. The remaining belt falls back to the guide and remains in a desired position for receiving the next portion of balancing weights. This manually operated balancing weight dispenser can be provided at significantly lower costs compared to the automated high performance balancing weight dispensers as known from the prior art. It is very robust and has no serviceable parts.

A device for performance testing and durability testing of an automobile tailgate. The automobile tailgate (1) includes a bearing platform (11), a mechanical mechanism (12), and a fixed beam (13), wherein the mechanical mechanism (12) includes a set of Lifting hydraulic cylinder, a group of overturning hydraulic cylinders, the cross-section of the fixed cross beam 13) is square, and is used to fix the tailgate of the car on the main beam of the car. The device (4), the hydraulic control device, and the position detection module; make up for the problem in the prior art that there is no vehicle lifting tail plate and no professional testing equipment.
